Extract

Little information is available on the behaviour of the base pressure on a body of revolution having a following body in its wake. A preliminary investigation for the case of axisymmetric rear body has been reported by Mishra and Chatterjee. Their experiments were conducted on a 20° included-angle blunt cone. Mishra and Das reported an investigation for the case of asymmetric rear bodies having the same diameter. These investigations indicate significant rear body effects on the base pressure.

In multistage rockets, the flow characteristics of upper stages could be seriously affected by the proximity of a lower stage after they separate from one another.
